Inflatable bed

ABSTRACT

An inflatable bed includes an upper body, a lower body, and a closed chamber space formed between the upper body and the lower body. The inflatable bed includes a plurality of connecting members therein. The connecting members are spaced a determined distance apart from each other and arranged longitudinally and transversely inside the inflatable bed for connecting the upper body with the lower body. Each of the connecting members is a thin ring-like structure. When the inflatable bed is inflated, the connecting members arranged in the longitudinal and transverse directions provide a bubble-like effect, thereby enhancing the comfort for the user to lie thereon. Further, the inflatable bed is light and small in size after collapsed, which is advantageous for camping and mountaineering.

FIELD OF THE INVENTION

The present invention relates to an inflatable bed, and moreparticularly to a connecting structure of an inflatable bed.

BACKGROUND OF THE INVENTION

For mountaineering or camping, people usually use a soft cushion toenhance the comfort of ling on the ground and stop the surfacetemperature. The soft cushion is made of a soft material, so it canenhance the comfort for the user to lie thereon. But, because of itssolid structure, the soft cushion is heavy in weight and large in size,so it is inconvenient for carrying. Therefore, an inflatable mattress isdeveloped on the market. Although it can reduce the weight and the sizeafter collapsed, the internal structure of the inflatable mattress isprovided with a number of pull strips. As a result, the inflatablemattress is still somewhat heavy.

Accordingly, the inventor of the present invention has devoted himselfbased on his many years of practical experiences to solve theseproblems.

SUMMARY OF THE INVENTION

In view of the shortcomings of the prior art, the primary object of thepresent invention is to provide an inflatable bed which is light inweight and comfortable for use and has a simple structure and can becarried conveniently and has a low cost and other advantages, meetingthe needs of industry and consumers.

In order to achieve the aforesaid object, the inflatable bed of thepresent invention comprises an upper body, a lower body, and a closedchamber space formed between the upper body and the lower body. Theinflatable bed includes a plurality of connecting members therein. Theconnecting members are spaced a determined distance apart from eachother and arranged longitudinally and transversely inside the inflatablebed for connecting the upper body with the lower body. Each of theconnecting members is a thin ring-like structure. When the chamber spaceinside the inflatable bed is inflated, the connecting members arrangedin the longitudinal and transverse directions provide a bubble-likeeffect, thereby enhancing the comfort for the user to lie on theinflatable bed. Further, the inflatable bed is light and small in sizeafter collapsed, which is advantageous for camping and mountaineering.

Preferably, the upper body and each of the connecting members are joinedtogether by a press-fit technique, such as high frequency heating, toform a bonded portion so that the upper body is connected with theconnecting member.

Preferably, the lower body and each of the connecting members are joinedtogether by a press-fit technique, such as high frequency heating, toform a bonded portion so that the lower body is connected with theconnecting member.

Preferably, the bonded portion may be of various shapes, such as acircle, a rectangle, a strip, or a polygon, but not limited thereto.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the present invention will now be described, by way ofexample only, with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 2, the present invention discloses aninflatable bed 1. The inflatable bed 1 comprises an upper body 11, alower body 12, and a closed chamber space 10 formed between the upperbody 11 and the lower body 12. The present invention is characterized inthat the inflatable bed 1 includes a plurality of connecting members 2therein. The connecting members 2 are spaced a determined distance apartfrom each other and arranged longitudinally and transversely inside theinflatable bed 1 for connecting the upper body 11 with the lower body12.

Each connecting member 2 is a thin ring-like structure. The upper body11 and the connecting member 2 are joined together by a press-fittechnique, such as high frequency heating, to form a bonded portion 13so that the upper body 11 is connected with the connecting member 2. Thelower body 12 is connected with the connecting member 2 in the samemanner.

According to the above-described structure, when the chamber space 10inside the inflatable bed 1 is inflated, the connecting members 2 spaceda determined distance apart from each other and arranged longitudinallyand transversely are inflated and connected between the upper body 11and the lower body 12 to provide a bubble-like effect, thereby enhancingthe comfort for the user to lie on the inflatable bed. Further, afterthe inside of the chamber space 10 is deflated (as shown in FIG. 3), theconnecting members 2 in the form of a thin ring-like structure are lightand small in size after collapsed, which is advantageous for camping andmountaineering.

The bonded portion 13 may be of various shapes, such as a circle. Asshown in FIG. 4, the bonded portion 14 is in the form of a strip tochange the appearance thereof.

Although particular embodiments of the present invention have beendescribed in detail for purposes of illustration, various modificationsand enhancements may be made without departing from the spirit and scopeof the present invention. Accordingly, the present invention is not tobe limited except as by the appended claims.
